摘　　要：为提高醋糟产氢废水的甲烷产量,研究了超声波对厌氧消化产甲烷的影响,以超声功率和超声时间为影响因素进行了响应面分析,实验结果表明,超声功率对厌氧消化产甲烷有显著的影响。响应面结果表明最佳的超声条件:超声功率为24 W,超声时间为29 s。基于最优超声条件下的醋糟产氢废水厌氧消化实验表明,超声能够显著提高醋糟产氢废水的甲烷产率,最高的甲烷产率为228 m L/g-VS醋糟,比未超声组提高了21%。甲烷菌细胞的传质效率的提高和较高的生物活性是甲烷产量提高的原因。To improve the biogas production of wastewater from vinegar residue,the effect of ultrasonic wave on the performance of anaerobic digestion is investigated. The analysis of response surface is carried based on the parameters of power and time of ultrasonic wave. The results show that the ultrasonic power has significant influence on anaerobic digestion,which is higher than the ultrasonic time. The optimum ultrasonic conditions are 24 W and 29 s. The methane yield could be obviously improved with ultrasonic wave under the optimum condition. The corresponding methane yield is228 m L / g-VS,which is 21% higher than the control group. The improvement of mass transfer of methanogen cell and the higher biological activity might be the main reason for higher biogas production.
